# Amending schedule settings When you select an existing schedule, all the current options for that schedule are pre-configured on the page. These are the settings that the report server will use to decide whether a particular schedule should be processed or not. You can Remove any schedule just by clicking the button. A small warning dialog will open, If you click Remove in the dialog the schedule will immediately be deleted from the database. The named reports that are included with the schedule are not affected, and any export files that have already been created by the schedule are also unaffected. It's just the schedule details themselves that are removed. Click Cancel to abort the action and the schedule remains unchanged. If you change any of the schedule's settings, you must Apply them before they become active. If you change any option, say for instance you change the Export file name format, The Apply button will appear at the bottom of the page. If you don't click this button, but instead select a different schedule in the list of Available schedules, or tab to a different page, all changes you have made will be lost, the original settings for the schedule will be retained. Any option can be changed, although the same rules apply as when adding a schedule, so you can't apply a change that would leave the schedule with no included reports, for instance, or with no selected destination. Warning error boxes are displayed with deatils of the error in these cases. One thing to remember when applying changes to a schedule is that when they are applied, any detail about the schedules previous run history is overwritten as well. This could lead to a schedule being run twice on the same day. For instance, if you change the details of a schedule which has already run that day, the last run date and next run date are reset, and the report server treats the schedule as if it is a brand new one. If the criteria are met, the report server will run the schedule regardless of whether it had already been run that day.
